Description

BACKGROUND HE INVENTION
1. Field of the Invention
The present invention relates to a motor and generator coupling device and more particularly pertains to driving single bearing generators with a hydraulic motor with a motor and generator coupling device.
2. Description of the Prior Art
The use of engine couplings is known in the prior art. More specifically, engine couplings heretofore devised and Utilized for the purpose of reducing engine stress are known to Consist basically of familiar, expected and obvious structural Configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements.
By way of example, U.S. Pat. No. 5,303,681 to Crofts; U.S. Pat. No. 4,501,982 to McMinn; and U.S. Pat. No. 4,579,926 to McMinn.
While these devices fulfill their respective, particular objective and requirements, the aforementioned patents do not describe a motor and generator coupling device for driving single bearing generators with hydraulic motor. Prior art either used a shaft, flywheel configuration, or the shaft is bored out by a generator manufacturer.
In this respect, the motor and generator coupling device according to the present invention substantially departs from the convention concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of driving single bearing generators with a hydraulic motor.
Therefore, it can be appreciated that there exists a continuing need for new and improved motor and generator coupling device which can be used for driving single bearing generators with a hydraulic motor. In this regard, the present invention substantially fulfills this need.
SUMMARY OF THE INVENTION
In the view of the foregoing disadvantages inherent in the known types of engine couplings now present in the prior art, the present invention provides an improved motor and generator coupling device. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved motor and generator coupling device and method which has all the advantages of the prior art and none of the disadvantages.
To attain this, the present invention essentially comprises a coupling having a generally cylindrical configuration. The coupler has an inner end and an outer end. The outer end has three studs extending outwardly therefrom. The three studs are dimensioned and are aligned for extending within three holes within a drive disc hub of a generator. A circular flange is secured to an outer wall of the generator and is disposed over the inner end of the coupling. A hydraulic motor is secured to the circular flange in communication with the generator.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are, of course, additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.
In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to be details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways.

As such, those skilled in the art will appreciate that the conception, upon which this disclosure is based, may readily be utilized as a basis for the designing of other structures, methods and systems for carrying out the several purposes of the present invention. It is important, therefore, that the claims be regarded as including such equivalent constructions insofar as they do not depart from the spirit and scope of the present invention.
It is therefore an object of the present invention to provide a new and improved motor and generator coupling device which has all the advantages of the prior art engine coupling and none of the disadvantages.
It is another object of the present invention to provide a new and improved motor and generator coupling device which may be easily and efficiently manufactured and marketed.
It is a further object of the present invention to provide a new and improved motor and generator coupling device which is of durable and reliable construction.
An even further object of the present invention is to provide a new and improved motor and generator coupling device which is susceptible of a low cost of manufacture with regard to both materials and labor, and which accordingly is then susceptible of low prices of sale to the consuming public, thereby making such a motor and generator device economically available to the buying public.
Even still another object of the present invention is to provide a new and improved motor and generator coupling device for driving single bearing generators with a hydraulic motor.
Lastly, it is an object of the present invention to provide a new and improved motor and generator coupling device including a coupler having a generally cylindrical configuration. The coupler has an inner end and an outer end. The outer end has three studs extending outward therefrom. The three studs are dimensioned and are aligned for extending within three holes within a drive disc hub of a generator. A circular flange is secured to an outer wall of the generator and is disposed over the inner end of the coupler. A hydraulic motor is secured to the circular flange in communication with the generator.
A standard generator shaft can be used without having it machined or bored out, or by using a through stud. The hydraulic motor can be easily removed from the generator without the need of special tools. The present invention can use any hydraulic motor with any shaft configuration. The coupler can be replaced if damaged or needs to be changed because another type motor is used. The motor bearing and generator bearing are aligned allowing for longer bearing life.
These together with other objects of the invention, along with the various features of novelty which characterize the invention, are pointed out with particularity in the claims annexed to and forming a part of this disclosure. For a better understanding of the invention, its operating advantages and the specific objects attained by its uses, reference should be had to the accompanying drawings and descriptive matter in which there is illustrated preferred embodiments of the invention.
